Application ledrseptcmber 10, 191'?. Serial No. 190,582.

To au ywit-ont t may conc-ern:

Be it known that I, EDWIN T. VVALmNG, citizen oi the United States, residing at Seattle, in the county oi King and State oit Washington, have invented certain new and useful improvements in Car Bolt-Seals, of which the following is a specification.

This invention relates to means for sealing car doors. 1f such doors are merely locked, thieves obtain false keys and, after committing a robbery, they relock the door, so there is no means of discovering the robbery without unlocking each car door.

The object of this invention is to provide a sealing device which, when broken open by anyone, cannot be rescaled excepting by authorized persons having proper seals, these seals being so conspicuous that an inspector or a local agent may readily detect the broken seal as the cars pass him. thus discovering the time and locality ot any such breaking.

To this end, my invention consists in the construction and combination of parts forining a car bolt seal hereinafter more fully described and particularly stated in the claims, reference being had to the accompanying drawings in which;

Figure 1 is a front view of one of my seals m service.

Fig. 2 is a horizontal section at line Fig. l, on a larger scale.

Fig. 3 is an interior tace view of a fragment of the bolt and one end of the seal as in service.

Fig. et is a vertical section oi a portion of the bolt and seal at dotted line (1j, Fig. 1.

Fig. 5 is aface view of the seal.

Fig. 6 is an inside face view of the stamped blank ot my car bolt in its preferred form.

Numeral T represents a portion of a common hasp, and 8 the staple for fastening a car door. The bolt 9, is usually secured to the car by a chain attached at the hole 10, and, when in service. the bolt is placed in the staple 8 outside of the hasp 7.

The bolt is U-shaped so that it will hang in the staple, and its two arms are substantially parallel. One end 11, ot the sealing strip 12, passing freely through a. slot in the bolt arm 16, enters the other arm 15, and is there secured by a Xed lug 13, engaging the strip in a slot 14, therein. Now,

ldevice is very little,

the other end 2d, o1 the strip 12, being pushed through the arm 15, is also engaged in its slot 14, by the lug 13, and the bolt is sealed, as shown in Fig. 1. The bolt may be economically shaped, with duly formed slots and lug, from half round iron, stamped on its liet tace with a die suitably shaped, at a single blow, before bending, as shown in Fig. 6. bent back on itself at line 21, the gain 17, hollowed to form a chamber as at 26, Fig. 2, will register with gain 19, forming a slot with the lug 13, left standing. The gain 19, is wide and deep enough to receive both ends of the seal strip lying flat, and the side edges of the chamber 26, touch down upon the strip when so located, but the arch ci the chamber is just high enough to permit one thickness only, of the strip to pass, at a time', over the lug 13. The gain 17 is a little narrower than the seal strip, as shown at 20, in Fig. 1t, thus holding down the edges of the strip and Jforcing the middle portion of its forward end to bend up in passing over the lug 13, and each end of the strip springs down behind the lug when the slot 14 is reached, and is thereby held from being withdrawn. The gain 18, is stamped more than twice the width of the strip to leave free thickness and width of the slot after the bolt is bent back upon itself and curved into due form as in Fig. 1. Rivets at 23 may hold the two ends of the bolt 9, rigidly together like a round bar. It is essential that the thickness of the slot at the sides of the arm 15, 'be barely enough to admit the two thicknesses 11, and 24, of the sealing` strip so that nothing can be inserted to pry the ends over the catch lug 13, and to hold the ends for the purpose of breaking the seal. To do this, take a firm hold of both ends of the sealing strip close to the inner side of the arm 15, and give a quick twist to tear the ends ofi" against the edge at 22. rlhe seal may then be removed from the arm 16, liberating it to be withdrawn from the staple 8, to unlock the door. A seal once broken cannot be restored so as to deceive the eye, because the jarring of the car will shake it loose.

rlhe original cost of this complete sealing and the expense of the strip of tin broken at each unlocking, is trivial. No tool is required either to apply When the half round bolt is Both locking and nn-V easily done with bare it or to remove it. locking it may be hands.

I claim,

l-` A ear bolt seal comprising a thin seal strip slotted near each end; a bolt slotted near one end to closely receive the two ends of the strip; a lug projecting from the Vbolt into the slot to engage the slotted ends of the strip, and a oliambered space above the lug to permit the entrance of but one end of the strip at a time.

2. A car bolt seal comprising a thin seal strip slotted near each end; a bolt slotted near one end to closely receive both ends of Copies of this patent may be obtain-ed foi` ve cents each, by addressing the Washington, D. C.

the strip; a lug rojecting from one face of the slot in the lbolt to engage the slotted ends of the strip, and archainber equaling in height, above the lug, of but one thickness 0f the strip, and narrower than the strip, whereby the strip will be held down at its edges and be forced to bend upward midway its width to pass over the lug. Y

In testimony whereof I'aiiX my signature in presence of two Witnesses.
